New install and not sure how do I get my controller to work?

I just installed HoloISO onto a Trigkey micro pc. It was pretty painless but I can’t get my XBox controller to work.

I can connect to it via Bluetooth in Steam game mode and in the OS but it doesn’t do anything. I tried using the Xbox wireless adapter but I read I need drivers but no idea how to get them since when I run pacman it tells me it’s unable to lock database but I don’t even have that file on my OS.

Any help would be appreciated. Thanks!
